Never head of this problem on the QUAD, only the TWIN.

In other posts the same SAT installer recommend the QUAD.

Hi all,
I should receive the lnb's on Tuesday. In the meanwhile I was thinking why when I have 1LNB I have a 10% signal improvement and not when I use the rail.

Hi again

Im sure you have said the same about 3 times but I thought the max you could get 75% to 80% and 75% on the rail??

Lots of transponders will give you different % As I said before maybe use 2-3 transponders with then single lnb at 13e then same on the rail, if you then have a difference then adjust to get the strongest signal and compare.

I also read about the twin being not as good as the single but I upgraded my dish and twin and most from 42 to 30w with my motor, so if I went for a single I would be much better lol

Your get there in the end mate :D

Hi Carsten,
I tried with a single LNB pointed on 13E and I got around 75... Now I managed to get: 100% on 28, 100% on 19.2, 90% on 23.5 and 73% on 13. Pretty good, no? I don't understand why even with a single LNB I get only 75% on 13E :confused:

Oh I see that was a type error. I got 90% on the 11354V. I never managed to get more than 75-80% on 12054H or 12341V.

Well I think that at this point I should leave everything like this. Anyway on my favorite channel on 13E the loss of signal on the rail it's just 3% (from 78 to 75) and not relevant. The only one that I'm a bit sad about it's the 23.5 on the rail there is 8% loss (from 91 to 82). I actually don't think that lnb would help. But I saw it in a local store for 15 euros.

Maybe you didn't read good my posts but I posted that without the rail there's a general 10% improvement on signal.

Hi.

I don't know it, so I have to find it on the internet. i see the With is 91 cm and the height is 70 cm. The width is 91 cm so it can receive more satellites located in a wider arc ( +/- 20 ) but all your wanted satellites are within 15 degrees. The height is only 70 cm. It must be smaller than your Triax 78.

If you want a larger dish go for the Triax 88. My other dish is a Triax 110 and they are good quality.

Regards Carsten.

P.S.: talking again with my friend he said that yes the visiosat it's less high but it's a multi focus dish. I don't know what that means and if it should be better then than the triax.

Hi.

To find out you can try:
If there is any difference with 13E between 78 and 88
1. When single LNB?
2. When Rail, but only 13E in the middle?
3. When Rail and 13E half way out?

Suggest you write down values for both 2 weak and 2 strong transponders.

Regards Carsten.

I agree :) But his saying his losing 10% when fitting to the rail, I haven't fitted mine yet and just compared the rail to a single holder and it looks a lot higher and slightly different angle too. Could that be the problem??

I think that I can't do that test because the dish, being bigger, can't be turned that far to 13 because the side of it then touches the barn wall.

Proberly. I tried several times to to tell Eliosfederico that if the hight of the LNB change he had to readjust the Dish Elevation to.

It is not a problem that the LNB sit higher when on the Rail, but you have to adjust the Dish Elevation. On mine I have a Triax Multiblock on a non Triax dish. I just mounted the Triax square
plastic on top of the NON Triax boom ( arm ) and used a longer screw. But I had to adjust my Elevation acordingly.

Yeah that was what I was hoping you would say :thum: I have much the same setup to do but don't want to remove my motor and read it shouldn't matter. Any chance you could post a few pictures of your setup plz

If he could match his single lnb then im sure a bigger dish or new lnb would help him too. :thum:
